Intentional Replantation of Failed Root Canal Treated Tooth

Abstract

Intentional replantation (IR) should not be considered a treatment of last resort. Long-term studies have shown that the success rate of IR is somewhat similar to periapical surgery. It is indicated in failed endodontic cases. However, many times, it is the last option to save the tooth when retreatment or surgical treatment is not possible and the patient cannot afford implant placement. This article presents a case of failed root canal treatment due to instrument separation extending periapically in mandibular first molar. The tooth was extracted atraumatically and the retrograde cavity was prepared and filled extraorally with mineral trioxide aggregate. Emdogain was applied to the root surfaces before replantation. The extraoral time was <10 min. The tooth was reimplanted in the socket and splinted with a composite fiber splint. The patient’s desire to save the tooth and the use of the best possible materials and techniques has resulted in the continued retention of the tooth.
